通过GraphAPI(python)发送邮件。邮件在投递的时候报错550 5.7.501 Service unavailable. Spam abuse detected from IP range.

通过https://learn.microsoft.com/zh-cn/graph/sdks/sdk-installation#install-the-microsoft-graph-python-sdk 使用了Graph API去发送邮件

代码如下：

# Code snippets are only available for the latest version. Current version is 1.x
import asyncio
import time
from azure.identity import ClientSecretCredential, DeviceCodeCredential
from msgraph import GraphServiceClient
from msgraph.generated.models.body_type import BodyType
from msgraph.generated.models.email_address import EmailAddress
from msgraph.generated.models.item_body import ItemBody
from msgraph.generated.models.message import Message
from msgraph.generated.models.recipient import Recipient
from msgraph.generated.users.item.send_mail.send_mail_post_request_body import SendMailPostRequestBody
# To initialize your graph_client, see https://learn.microsoft.com/en-us/graph/sdks/create-client?from=snippets&tabs=python
scopes = ['https://graph.microsoft.com/.default']
# Multi-tenant apps can use "common",
# single-tenant apps must use the tenant ID from the Azure portal
credential = ClientSecretCredential(
    client_id='',
    client_secret='',
    tenant_id='',
)
graph_client = GraphServiceClient(credentials=credential, scopes=scopes)
async def get_user():
    user = await graph_client.users.by_user_id("邮箱").get()
    if user:
        print(user)
        print(user.user_principal_name)
#asyncio.run(get_user())
async def send_mail():
    
    try:
        #print(request_body)
        request_body = SendMailPostRequestBody(
            message = Message(
                subject = "测试测试",
                body = ItemBody(
                    content_type = BodyType.Text,
                    content = "测试测试",
                ),
                to_recipients = [
                    Recipient(
                        email_address = EmailAddress(
                            address = "邮箱",
                        ),
                    ),
                ],
            ),
            save_to_sent_items = True,
        )
        response = await graph_client.users.by_user_id("邮箱").send_mail.post(mailbericht)
        time.sleep(2)
        print(response)
    except Exception as e:
        print(e)
asyncio.run( send_mail())

以上代码没有报错，但是邮箱在投递的时候报错了

Delivery has failed to these recipients or groups:

{邮箱}
Your message wasn't delivered because the recipient's email provider rejected it.
